The design began with a user interface proposal (consisting of a new user interface (UI) style and color schemes) that was shown to public to gather first reactions from a restricted audience. Based on feedback the style evolved and eventually interaction diagrams were made to make sure that the functionality was both possible and logical to implement. The interaction diagram consisted of premade visualization mockups of the different screens (made to fit the actual display size of the target device), which included most of the elements to offer the full functionality. The diagrams were then presented to usability experts to be initially evaluated and commented upon.

The design decisions were then implemented with Symbian C++ and a prototype was produced to test the theories in practice and to gain information about the users. The implementation itself took advantage of emerging technologies such as 3D acceleration to make it possible to use visually rich user-interface elements and animations. These were produced to help users to understand what is happening within the application as well as offer information that would be hard to show with the traditional user-interface style already established on S60 devices.

The prototype was then evaluated against already existing software in a user trial. A total of eight recruited to perform various tasks on both of the applications and rate their experiences.

The outcomes of the user-study were positive, with the majority of the users (five out of eight) preferring the prototyped interface to the existing and fully working solution. This was considered as a good result given the qualitative feedback from the users, the differences between the technical maturity between the applications (a prototype versus a production quality application already distributed on the Internet) and finally the change resistance of already experienced S60 test participants. Also, some of the findings emphasized the importance of the holistic experience and look-and-feel over a pure set of technical features and merits.
